Abstract

The invention provides an optical module, which comprises a photoelectric conversion unit, a processing unit, a first resistor, a diode, a capacitor, a second resistor and a field-effect transistor, wherein a first end of the first resistor is connected with a first end of the capacitor and a source electrode of the field-effect transistor; the first end of the first resistor is used for introducing a high level; a second end of the first resistor is connected with a positive electrode of the diode; a negative electrode of the diode is connected with a second end of the capacitor, a grid electrode of the field-effect transistor and a first end of the second resistor; a second end of the second resistor is grounded; a drain electrode of the field-effect transistor is connected with a power supply end of the photoelectric conversion unit; an output end of the processing unit is connected with a positive electrode of the diode, and is used for providing a low level to the positive electrode of the diode after the high level is introduced at the first end of the first resistor. The optical module provided by the invention cannot be easily damaged during hot plug.

Description

technical field [0001] The invention relates to photoelectric conversion technology, in particular to an optical module. Background technique [0002] The optical module has the function of photoelectric conversion. Its transmitting end is used to convert electrical signals into optical signals, and transmits optical signals through optical fibers, and its receiving end is used to convert received optical signals into electrical signals. Because optical fiber transmission has the advantages of high frequency, large capacity, high transmission rate, and high stability, optical modules have been widely used in modern information exchange, processing, and transmission. [0003] An optical module usually includes a power supply control unit and a photoelectric conversion unit. In order to protect the photoelectric conversion unit, the hot-swappable optical module usually uses a power supply control unit to realize soft power-on, that is, when the optical module is connected to ...
